William wanted to tell him how terribly bad his techniques were, and he had to restart learning all of them from the rock bottom.
"Ahem… What I can say is that your luck is great…" William paused before adding, "In fact, all of your techniques aren't that good. You committed many mistakes and, in my opinion… You'll need to restart learning all of them from the start."
"..."
William knew he was going hard over this good lad. But there was no other way to say it but in such a way. William knew trying to amend these techniques wasn't going to work.
These techniques were taught on the wrong basis. If William tried to advise him right now without breaking all these techniques apart, teach John the right techniques, then this lad wasn't going to be taught anything at all.
"Can you please explain in more detail?" John kept his silence for a few minutes while opening and closing his mouth repeatedly, as he didn't know what he should say.
